This office chair has a ruffled seat and backrest. There is a hatch on the underside of the seat that allows the backrest rigidity to be adjusted.

Good used condition. There are light scratches and stains. A bit dusty, needs to be cleaned.

"The 'Figura' makes use of an existing office chair produced by Vitra, but by "dressing" it with stylish upholstery, Bellini conceals the high-tech aspect. The belt, pleat, and impeccable tailoring exemplify the Italian flair for haute couture and give the chair personality and elegance. The wide belt does suggest the presence of a waist, which implies movement where we normally expect it to occur in the human body. The upholstery, which is zipped together, can be removed for cleaning and change of colors."
